RAPOSO, Adriana Andrade; SCHETTINI, Antônio Pedro Mendes and MASSONE, Cesare. Concurrent primary and secondary myiasis on basal cell carcinoma. An. Bras. Dermatol. [online]. 2012, vol.87, n.2, pp.292-295. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962012000200016.
Myiasis is a disease caused by infestation of fly larvae in human and other vertebrate tissues. It is a skin condition common in tropical and subtropical countries and its predisposing factors are: chronic diseases, immunodeficiency, poor hygiene, senility, psychiatric disorders, skin cancers and ulcerated mucosae. We report the case of a healthy patient who after traumatic injury of a preexisting lesion showed a tumor on the dorsal region parasitized by fly larvae. The histopathological examination performed for the diagnosis of skin neoplasm surprisingly revealed the presence of a partially degenerated larva with characteristics of Dermatobia hominis, suggesting an association of primary and secondary myiasis on basal cell carcinoma.
